Submit the tender with all mandatory returnables. The documentation evaluation starts when submissions are opened and assessed for the first time. Failure to meet any level 1 basic compliance requirement results in automatic disqualification. Mandatory returnables include: a letter from Eskom confirming product approval and TEAP listing (or, if the OEM lacks such a letter, a letter on company letterhead listing all Eskom approved products and model numbers/product codes); if the tenderer is not the OEM, an authorisation letter confirming agreement with the OEM. For TEAP listed products, technical submissions are not required, but the above documents must be provided.

For TEAP listed products, mandatory tender returnables: 1) Letter issued by Eskom confirming product approval and TEAP listing; 2) If OEM does not have such a letter, a letter on company letterhead listing all Eskom approved products and model numbers/product codes; 3) If the tenderer is not the OEM, an authorisation letter confirming agreement with the OEM. Tenderers submitting TEAP listed products are not required to submit technical submissions but must provide the above documents.

The evaluation has two main parts: documentation evaluation and factory evaluation. Documentation evaluation checks key tender deliverables. Technical evaluation criteria include: cable dimensions, detailed description, drawing number, revision number, dimension of the cable, and detailed description provided in the title. For testing performed within the last 10 years, the supplier gets 100% and loses 20% for each additional year. Complete failure to comply with sub-clauses results in a score of 0%. If a threshold score is achieved but 10% outstanding aspects remain, the tenderer must address non-compliant aspects as part of possible contract award. Drawings (weight 6) must include drawing number, revision, dimensions, title description, approval and date, and cable sheath marking. Annexure A sample verification includes construction criteria such as marking, materials, dimensions, stripping cord, UV stability, and drum compliance.

The technical evaluation criteria are set for evaluating tender submissions for concentric cable with tinned copper and coated steel without communication cores for Eskom. The cable must comply with Eskom standard 240-61704085. Tests must be performed at accredited testing facilities. For TEAP listed products, the manufacturer must provide proof of Eskom approval. The evaluation includes documentation evaluation and factory evaluation. The cable drum must be made in accordance with Eskom standard 240-61704085, and marking of the cable drum must comply with the same standard. The manufacturer must meet all requirements; failure to meet any one results in automatic disqualification.

The evaluation methodology includes two main parts: documentation evaluation and factory evaluation. Documentation evaluation is performed by Eskom evaluating representatives when submissions are opened. Factory evaluations are only performed on submissions that meet all Level 1 basic compliance requirements. Eskom Commercial arranges factory visits and invites technical representatives. The factory evaluation covers cable manufacturing plant evaluation including design capability, type tested compounds, extrusion lines, manufacturing processes, sample and routine testing.

This is an Eskom engineering standard for low-voltage cable systems, not a procurement specification. It sets out technical requirements for planning, design, installation, and testing of LV cables, including compliance with SANS 1507, cable sizing, installation depths, bending radii, earthing, and jointing practices. It references numerous Eskom distribution standards and SANS codes. It is not a tender-specific scope of work.

{"closingDate":"22 July 2021"}

The extracted document does not specify eligibility criteria such as CSD registration, tax clearance, B-BBEE requirements, or local content percentages. Bidders should refer to the full tender documentation for these requirements.

This standard has been prepared to establish and promote uniform planning and design for low-voltage cable

distribution or reticulation systems. The Planning and Asset Design departments should take cognizance of

the constraints regarding system operation, system protection considerations and of the design application

within the Eskom standards and South African National Standards. This document contains the requirements

for installation of low voltage cable systems. The installation, construction and commissioning of low voltage

cable systems shall be in accordance with standard requirements to avoid an unnecessary premature failures

as this type of network construction and maintenance is generally expensive. The affected departments should

take into consideration proposed future developments and adjacent supply areas.

2. Supporting clauses

2.1 Scope

This standard covers the general requirements for a low voltage underground cable distribution system

throughout the project life cycle, i.e. concept release approval at planning, definition release approval at design,

execution release approval at construction and final release approval at commissioning. These systems are

normally fed from medium voltage/ low voltage mini-substations or ground-mounted transformers connected

through cables and are used to supply consumers at low voltage. A low voltage cable system would typically

consist of all or part of the following:

a) Mini-substations feeding LV meter kiosks and meter panels;

b) Ground-mounted transformers feeding meter panels with supplies up to 500 kVA;

c) LPU and SPU meter panels;

d) SPU meter kiosks;

e) Secured meter kiosks; and

f) LV feeder cables, service cables and customer cables.

This standard also covers the requirements for LV cable terminations onto overhead lines.

2.1.1 Purpose

The main purpose of this document is to establish and promote uniform designs for low-voltage cable

distribution/ reticulation systems.

2.1.2 Applicability

This document shall apply throughout the Clusters of Eskom Distribution Division.

2.3 Definitions

2.3.1 General

The definitions in accordance with NRS 000 and SANS 10198-1. The definitions of the terminology used in

this standard are as follows:

Definition Description

Compacted Crown A layer of compacted soil above the natural ground level along the trench.

Customer cable The customer’s cable, used to connect the customer’s plant to the supply at the

metering point. The customer cable uses a separate neutral and earth

conductor, so it may be three core armoured cable (for a single-phase customer)

or four core armoured cable with a separate earth continuity conductor for a

three-phase supply.

Low Voltage A voltage of r.m.s. value not exceeding 1000 V.

LV feeder cable The supplier’s three-phase, LV cable used to distribute electricity from the

miniature substations to the metering kiosks. LV Feeder cables use a combined

neutral and earth system, so four core armoured cables are used. No Customers

are supplied directly from a LV Feeder.

LV service cable The supplier’s LV cable, used to supply electricity from the metering kiosk to a

customer’s premises. The service cable uses a combined earth and neutral, so

it may be a two-core armoured cable (for single-phase supplies) or a four-core

armoured cable (for three-phase supplies).

Meter panel It is the enclosure for mounting plate for meters, moulded case circuit breaker

(MCCBs), plugs, and other accessories (but not for busbars)

Metering Kiosk It is the enclosure used to provide a safe and convenient point at which to

connect multiple customer cables to the bus bar and feeder cable via meters and

circuit breakers

Miniature substation A factory-assembled and tested free-standing unit that is suitable for use in an

(or mini-substation) area accessible to the public, that comprises a transformer, an equipped

medium-voltage compartment and an equipped low-voltage compartment and

that is suitable for connection to underground cables (NRS 004).

2.3.2 Disclosure classification

Controlled disclosure: controlled disclosure to external parties (either enforced by law, or discretionary).

protective earth conductor and consumer earth terminal to the supply earth terminal at the point of supply.

1. High resistance faults on LV networks are discussed in 34-609.

2. A separate earthing conductor is therefore not required up to the customer’s point of supply. The neutral conductor

serves as a combined protective earth and neutral (PEN) conductor.

3. Application of lugs on the armour wires and connecting them to the earth bar or earth terminal may only be done in

existing installations where there are no gland plates provided. In this case, all the armour wires are to be used.

4. The requirements for the MV and LV earth electrodes associated with mini-substations, pole mounted transformers

and ground-mounted transformers are described in 240-56030635.

5. The supply earth terminal, in turn, is connected to the protective earth and neutral (PEN) conductor of the LV system.

6. Where split meter kiosks are installed, a service cable having a PEN conductor is used to supply the consumer. The

service cable PEN is connected to the LV feeder cable PEN at the kiosk.

3.8 Metering Applications

The metering application and requirements shall be in accordance with 240-75661043.

3.9 Low-Voltage Cables

After the installation of LV cables at the minisubstation’s LV compartment and kiosks, the plinths shall be

backfilled and sealed (using a concrete screed). An approval shall be obtained from the design engineer prior

to any deviations from the design package/ document.

3.9.1 Cable Selection

have either copper or aluminium conductors.

b) The LV cables to be terminated onto LV compartment of the minisub or onto the bus bar of the

metering kiosk by means of indoor termination kit in accordance with D-DT 0830 relevant sheet.

c) The LV feeder cable can be terminated using bi-metallic torque shear lugs and suitable insulating

sleeves.

d) If crimp lugs are used, then the following shall apply:

1. For copper conductor LV feeder cable, terminate by using copper crimp lugs and suitable

insulating sleeves.

2. For aluminium conductor LV feeder cable, terminate by using torque shear lugs and the

suitable insulating sleeves in accordance with relevant sheet of D-DT 0830.

e) The LV cables to be terminated onto the overhead lines by means of outdoor termination kit in

accordance with D-DT 0831, D-DT 0832, D-DT 0833, D-DT 0834 or D-DT 0835.

g) The world market price of copper and aluminium dictates the type of conductor that is most cost

effective at any time, however copper conductors have been preferred for the following reasons:

1. The core and outer diameters of a copper conductor cable are smaller for equivalent

ampacity than an aluminium conductor cable – facilitating easier working when jointing and

terminating;

2. Due to the sizes required, torque shear lugs cannot be used in all applications. cold flow

properties of aluminium can result in hot connections if not crimped properly; and

3. Copper conductor cables do not require bi-metallic lugs when connecting to equipment fitted

with brass stem bushings.

h) Aluminium cables can be considered as a theft mitigation measure.

i) Low voltage feeder cables shall be four-core, three-phase armoured cables.

j) Service cables may be any one of the following:

1. Two-core armoured cable for single-phase supplies;
2. Four core armoured cable for three-phase supplies; and
3. Single core aluminium conductor armoured cable for LPU supplies > 500 kVA.

k) Customer cables will typically be either two core armoured cable for single-phase supplies or four

core armoured cable with an earth continuity conductor (ECC) for three-phase supplies.

l) For the purpose of labelling of drawings and purchasing, a method of cable coding has been

implemented by Eskom (see D-DT 0856).

m) The cable cross-sectional area shall be chosen to suit the network load and volt drop requirements

as well as the prospective fault level of the system. The symmetrical and earth fault levels of the

cables are given in tables 1 to 4 below. These fault levels based on K values of 0,115 and 0,076 for

Cu and Al conductors as supplied in SANS 10198-4 and SANS 10142. The formula used for

calculating these values are:

This document describes the technical evaluation criteria for tender submissions by external contractors intending to supply overhead phase conductors. It covers the evaluation process for ACSR, AAAC, and AAC conductors, including desktop and factory assessments. The criteria are tabulated in annexures and this document assists with new conductor contracts without replacing the existing phase conductor specification (240-152844641).

Closing date and time are not stated in the provided text. No briefing or site visit dates are mentioned.

Submit the completed tender returnables, including the A/B schedules, conductor schedule summary (Annexure A), type test report summary, and the analysis file for ACSR, AAAC, and AAC conductors. The technical evaluation includes a desktop assessment and a mandatory factory assessment to verify manufacturing capability. Bidders must achieve a minimum score of 70% in both the desktop and factory evaluations to qualify. Type test reports must be provided for each conductor tendered, with provisions for conductors not previously manufactured. Calibration certificates for all testing equipment and evidence of competent technicians operating the equipment are required. The tenderer must also submit a history of external customers supplied with similar products, affiliations with international organisations or experts, and sample technical drawings demonstrating design capability.

Tenderers must submit completed A/B schedules for all proposed conductor types, a Conductor Schedule Summary (Annexure A), type test report summaries, and a file with analysis of ACSR, AAC, and AAAC manufacturers. The returnable list includes 47 possible conductor types, with scoring based on the number of completed schedules and available type test reports.

The technical evaluation procedure involves a desktop assessment and a factory assessment. The desktop evaluation scores the tenderer's ability to manufacture conductors, including drawing down raw aluminium, producing complete stranded conductors, and complying with Eskom specifications. The factory evaluation verifies the supplier's capabilities through on-site assessment. The final scoring combines A/B schedules (50%) and analysis of ACSR, AAAC, and AAC conductor information (50%), with an overall minimum threshold of 70%. Bidders must also provide a history of external customers supplied with similar products, affiliations with international organisations or experts, and sample technical drawings. Type test reports must be submitted for each conductor tendered, with provisions for conductors not previously manufactured.

This document aims to describe the criteria which will govern the evaluation of tender submissions by external

contractors intending to supply overhead phase conductors. The criteria for each phase conductor type are

tabulated in the annexures at the end of this document.

The criteria necessary to perform both the desktop and factory evaluations are outlined. This document is

meant as an assistive document for new conductor contracts and does not replace the existing phase

conductor specification (240-152844641).

3. Technical Tender Evaluation Procedure

The technical evaluation procedure is specific to each item type. The items include ACSR, AAAC and AAC

conductors.

The complete evaluation of any potential supplier would involve a desktop evaluation as well as a factory

evaluation. The factory evaluation is necessary to verify if the supplier possesses the capabilities which they

have documented in their tender submissions.

3.1 Desktop Evaluation

The desktop evaluation forms the first aspect of the assessment. During this process, the tender

documentation submitted by potential suppliers is evaluated against the criteria listed in the attached

ANNEXURES A, B, and C. Generic A/B schedules are provided in the document, but the full schedules and

tick sheets will be available in excel format with the tender enquiry package. The Eskom evaluating

representatives will go through the details of the returnable submissions that are required and will ensure that

the Gatekeeper criteria are met. If submissions that receive a “No” on any of the Gatekeeper criteria, the

supplier will not be able to proceed to the Desktop Evaluation and therefore will fail the technical evaluation.

From a technical perspective, the submitted documentations should consist of but not be limited to:

3.1.1 Conductor Evaluation – the tenderers will be scored according to score sheets in

Annexures A, B, and C once they meet the Gatekeeper requirements, also found in

the Annexures.

a) Specifications of the various phase conductors which the supplier proposes, and has the capability

to, manufacture and supply. Tenderers are required to completely populate the relevant A/B

schedules (found in Annexure C) submitted for all phase conductors that can be manufactured. A

minimum or nearest equivalent (to be approved by Line Engineering Services) to the greased and

ungreased options of phase conductors must be submitted.

b) Tenderers are required to submit type test reports for every conductor tendered upon. Where type

tests are not available for conductors not previously manufactured (e.g. IEC 630 ACSR) type tests

will be required after order placement but before full production of the order (Eskom and the supplier

shall agree on the timeframes for the submission of type tests)

c) The supplier shall submit phase conductor information for use in PLS-CADD software applications

with the cable creep test co-efficients as requested and within a year of contract award.

d) Tenderers to submit details of manufacturing premises, location, staff and equipment, testing

facilities, manufacturing lead times.

e) Tenderers shall ensure that they cater for the manufacture of previously unsupplied conductors that

may be requested during the contract lifetime. Tenderers shall also produce all the above- mentioned

information for each of the unsupplied conductors they wish to supply as part of the contract.

f) The phase conductor technical tender returnable shall have the following deliverables:
